Assuming negligible air resistance, the acceleration of a projectile near the Earth's surface is always the gravitational 9.81 m/sec/sec downwards, regardless of where in the trajectory the projectile is.
Since I have read that the path of a projectile is always a parabola, I must say no. The parabolic shape of a projectile's path results from the combination of the force and direction with which it is launched and its weight.A ball rolling down a slope, is not Projectile Motion. While a cannon ball can be used to be a projectile, as far as Physics goes, that is not how it is operating at the moment (rolling down a slope).

No. It always indicates that the object is not accelerating.
No. It always indicates that the object is not accelerating.
D= vyt+1/2at2 a = (v2-v1)/t These are the two most basic formula that are used to figure out projectile motion questions, combine with SOHCAHTOA (trig) to solve simple projectile motion problems. Remember the horizontal velocity is always constant.
